no, no, no for the love of god, no.
NO.
it's my honest belief that if people cannot play a game right, they shouldnt play it at all. half the games i join nowadays in blackops on ps3 are full of people who do nothing but hide in one little spot the whole game. i got 7 kills with one grenade on firing range because of all the campers in that tower with the ladder going up to it.
imho:
Camping = 100% no-skill
Ghost perk w/ surpressed machine gun of any kind = 100% annoying
Surpressor on a SPAS-12 = 100% pointless and stupid (how could treyarch do that?)
this is the way you should use ghost:
Get a sniper rifle, find an area with a decent tactical view, pop some skulls. don't use ghost on a class with a machinegun/shotgun.
back on topic though, the camping has progressively gotten worse since W@W. Mw2 was such a horrible campfest and blackops quickly became just as bad. god knows what it'll be like on the new maps for the first few months..... T.T
